If you're looking for a unique way to fill in a space, consider split back stitch! I used split back stitch to fill in the body of this goldfish, and love how easily it both follows a curve and can create fun texture and depth to a piece.
There are so many ways to fill in a space; this is just one option!
I've written out the steps for filling in a space with split back stitch here, but if you're like me, videos are way easier to understand! That's why I've also included a video below of me using split back stitch to fill a space.
STEPS:
Begin by outlining your shape with split back stitch. Split back stitch is very similar to back stitch; however, instead of going through the hole created by your first back stitch, you'll go through the floss itself - thus, splitting it.
To fill, continue with split back stitch, keeping each new line of stitches as close as possible to the line you just stitched.
For more delicate details, use fewer strands of floss and/or a shorter stitch lengths.
